Product Description Product Description Epoxy fiberglass rods and tubes are high-performance composite insulation components made of epoxy resin reinforced with fiberglass. They are widely used in surge arresters as insulating support members. These products provide excellent electrical insulation, mechanical strength, and environmental resistance, making them ideal for various voltage levels in outdoor and indoor applications. Product StructureThese rods or tubes are manufactured by pultrusion or filament winding process, using ECR glass fibers impregnated with epoxy resin. The cross-section is typically round, and the surface is smooth. Multiple diameters and lengths are available to suit specific installation requirements in surge arrester designs.
